1.Allow thetool t oreach f ull s peed b efore touching tool t othe work
surface.
2.Applyminimum pressure t o work FIG. 14

high speed. Sanding rateisgreatest
when t hetool o perates athigh speed.
3.Maintain a 5 °to15 °angle b etween the ..........
toolandworksurface. Thesanding 5_15°
discshouldcontact a pproximately
one inch ofwork surface.
4.Move the tool c onstantly inastraight line toprevent burning and
swirling ofworksurface. Allowing thetool t o restonthework
surface without moving, ormoving t hetoolina circular motion
causes burning and swirling marks o nthe work surface.

Mounting and Using Wire Brushes
and Wire Wheels
Wire cup brushes or wire wheels screw directly on the grinder
spindle without the use of flanges. Use only wire brushes or wheels
provided with a 5/8"-11 threaded hub. A Type 27 guard is required
when using wire brushes and wheels.
CAUTION: Wear work gloves when handling wire brushes
and wheels. They can become sharp.
A CAUTION: Wheel or brash must not touch guard when mounted
or while in use. Undetectable damage could occur to the accessory,
causing wires to fragment from accessory wheel or cup.
MOUNTING WIRE CUP BRUSHES AND WIRE WHEELS
1. Thread the wheel on the spindle by hand.
2. Depress spindle lock button and use a wrench on the hub of the
wire wheel or brush to tighten the wheel.
3. To remove the wheel, reverse the above procedure.
NOTICE: Failure to properly seat the wheel hub before turning the
tool on may result in damage to tool or wheel
USING WIRE CUP BRUSHES AND WIRE WHEELS (FIG 15, 16)
Wire wheels and brushes can be used for removing rust, scale and
paint, and for smoothing irregularsurfaces.
1. Allow the tool to reach full speed before FIG.15
touching the tool to the work surface.
2. Apply minimum pressure to work surface,
allowing the tool to operate at high
speed. Material removal rate is greatest
when the tool operates at high speed.
3. Maintain a 5°to 10° angle between the tool and work surface for
wire cup brushes.
4. Maintain contact between the edge of the wheel and the work
surface with wire wheels.
5. Continuously move the tool in a forward and FIG.16
back motion to avoid creating gouges in the
work surface. Allowing the tool to rest on the
work surface without moving, or moving the
tool in a circular motion causes burning and
swirling marks on the work surface.
